It took the Wrights more than three years to obtain the patent that they originally sought in 1903,
but when it was finally granted, it was exactly what they wanted. Following the solid advice of their
experienced patent attorney, Henry A. Toulmin of Springfield, Ohio, the Wrights decided to patent not
just the mechanisms that allowed them to warp or flex a wing but, more importantly, to patent the idea
of warping itself. Toulmin advised the brothers that obtaining a very broad patent able to defeat all
challenges in court would take time, and that, in the meantime, they should not allow details of their
invention to become public. The Wrights therefore decided on secrecy until their patent was secured,
during which time they continued to work at building a real, practical machine.

During the spring of 1907, Wilbur spent nine weeks in Paris without Orville to negotiate for the
sale of their machines to the French. He was accompanied by Hart O. Berg, an American who lived in France
and worked for Flint & Company, the firm that Wilbur and Orville had hired to handle their foreign business.
Orville joined Wilbur at the end of July; until that time, they communicated by letter and by cable.
To ensure secrecy, the brothers used a standard Flint & Company code for their overseas cable communications.
This telegram contains an original coded message and Wilbur's handwritten decoding, or translation.
Since their messages were typically cryptic as well as coded, the brothers sometimes misunderstood each other.

The Wrights had offered their machine for sale to the U.S. War Department as early as January 1905,
but three years had passed before the federal government developed serious interest. In the first formal
Army airplane contract signed by the Wrights and the U. S. Signal Corps, the brothers promise to deliver,
in two hundred days, a heavier-than-air flying machine that meets the Corps' Specification No. 486.
The major specifications stipulate that the machine be capable of carrying two persons at a speed of
forty miles per hour, staying in the air for at least one hour, and landing without serious damage.
For this, the Wrights received $25,000.
